Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head.
Grade 5 High Tensile Hex Bolt (Inches)

They are considered structural-grade bolts and are used in high-strength and load-bearing installations, such as automotive, construction, and machine industries. Under the metric grade of the ISO (International Standard Organization), the bolts are classed from 4.6 to 12.9, where the hardness, ductility, wear, heat resistance, and tensile strength of the bolt rise with the numerical value. The class of the bolt is punched into the head of the bolt and is a visible indication of a metric bolt. The six sides of the hex head allow a firm grip during tightening or loosening. This bolt is used with a torque wrench/gun to reach the proper preload of the bolt. Commonly with a zinc (galvanized) or plain (oiled) finish, these bolts can come with a shank and thread or with a full-threaded grip length. The bolt's diameter, length, and class depend on the manufacturer’s specifications.
